Investments in energy efficiency in the residential sector (27% of EU final energy demand) may also provide economic benefits at different levels of the economy. These benefits may not be realized because of barriers, which are typically reflected in implied discount rates. BRISKEE (Behavioural Response to Investment Risks in Energy Efficiency) provides evidence-based input to energy efficiency policy design and evaluation, thereby supporting the market uptake of energy efficiency technologies in the EU residential sector. It contributes to the work programme by addressing the interrelations between microeconomic factors, sectoral energy demand and macroeconomic effects, relying on a consistent methodological framework implemented in 5 work packages: • Provide empirical evidence for the magnitudes of discount rates accounting for differences across households, technologies and countries, and assess their effects on the diffusion of efficiency technologies in the EU (micro-level). A multi-country survey (1000 interviews per country) will be carried out and analyzed econometrically. • Explore the impact of time discounting and risk preferences (and of policies affecting those factors) on the diffusion of energy efficient technology and energy demand in the EU residential sector until 2030 (meso-level). Established bottom-up vintage stock models will be employed for appliances (FORECAST-Residential) and for buildings (Invert/EE-Lab). • Explore the macro-level impacts of changes in microeconomic decision-making and of energy efficiency policy on employment, GDP and exports in the EU until 2030. This involves simulations with an established macro-economic model for the EU (ASTRA). • Provide evidence-based recommendations for key energy efficiency policies and input for impact assessments and policy analysis at the three levels of analysis. • Communicate and disseminate empirical findings to policy makers, national experts, the research community and the general public.

Building methodology in skyscrapers marked a turning point in the construction sector. Due to the high altitude of those buildings, the only way of building them is a crane that rises in the same manner the skyscraper does. The main objective of the AIRCRANE project is to complete, qualify, standard setting and demonstrate in real working conditions a self-climbing telescopic crane (AIRCRANE) for the construction of full-concrete towers for wind turbines, at very low cost compared to current market solutions. This new solution has been inspired by the skyscraper’s building methodology. As a consequence of the development of this new crane, the second objective will be the introduction in the market of a new full-concrete tower with no height limit and with a new patented procedure of building that will bring reliability, time saving, quality and workers safety. In the current decade the main trend in the wind energy sector is to decrease the costs of the energy produced by wind turbines. One of the main strategies is the installation of the rotor axis (as well as nacelle and generator) at higher heights, as much as possible, where turbulences are minor and the efficiency of the equipment is higher. However, the wind industry has found some technical and economic constraints given by the construction of steel towers. This constraints are related to: size limitations in transport (larger diameters of tower segments), cost increase for heights greater than 100m., vibrations, etc.. Full concrete towers, built with precast concrete elements are a feasible solution: easy to transport, more durable (~50 years vs. ~25 years of steel), less vibrant, less required maintenance, etc. Another advantage is that concrete annual average price is significantly lower than steel. The development of the new AIRCRANE will help in the construction of full concrete towers, to reach heights unreachable with conventional nowadays crawler cranes (>140m) and at a much lower cost.

The Integrated Roof Wind Energy System (IRWES) is the breakthrough solution overcoming all shortcomings of existing renewable energy solutions. IRWES is a roof-mounted, elegant structure with an internal – nonvisible – turbine making smart use of aerodynamics. It is more efficient than any existing urban windmill, and more efficient per area than PV panels when mounted on roofs higher than 20m. This novel system has highest efficiency based on IP protected and tested technology (TRL6). It reduces the payback time by effectively producing electric power in both high and low wind speeds resulting in both more efficiency and operational hours. The Netherlands counts 35.000 buildings suitable for application with attractive ROI, while greatest impact is achieved in Europe where 1/6 of the population lives in high-rise buildings. Customers have already committed to 25 units after demonstration. IRWES is a business opportunity ready for large growth, to serve the – until now – unreachable segment of local renewable energy supply to high buildings, while seamlessly aligning with the Horizon 2020 Work Programme objectives. Moreover, IRWES addresses European and global challenges such as reducing the risk of carbon “lock-in”, offering sustainable and affordable alternatives to rising electricity prices as well as closing the gap between R&D, innovation and entrepreneurship. Its market excellence is defined by meeting the important customer demands differentiating in aesthetical integration and customization; creating more value as an outstanding, attractive solution. Our business objectives have been outlined in 8 Work Packages to prepare the IRWES mass-market launch, positioning it as a game changing solution on the European market. Based on rigorous studies and feasibility assessments, already performed, we present a solid business plan that incorporates a commercialization strategy and a financing plan to underpin the foreseen market launch and growth strategy of IRWES.

The project focuses on the Concentrated Solar Power sector (CSP). A HTF (High Temperature Fluid) is a liquid used to heat transport and transfer it in a solar thermal plant. Nowadays, most of the plants (both parabolic or tower technology) use synthetic oil as the HTF, which reaches working temperatures up to 400ºC. However, high temperature cycles accelerate oil degradation and then impurities appear. The appearance of impurities is a problem that affects the operation and the integrity of the current CSP power plants. Oil regeneration is a common operation in many industrial processes, however, there is no specific solution for CSP power plants that meet their efficiency and costs related needs without risking their profitability. By now, CSP power plant operators treat the oil periodically in external far regeneration plants that provide a standard fluid distillation with low efficiency and big fluid loses that represent great costs. Due to sector’s current constraints to increase power plant’s capital investment and operation & maintenance costs new more efficient, and with more flexible management models, HTF regeneration solutions are required. TRANSREGEN is a new high efficiency oil regeneration system that implements a compact & transportable design in order to extend fluid generation and waste management possibilities. Having successfully designed & validated TRANSREGEN technology in a relevant environment, the overall objective of this project is the demonstration of the final solution in solar thermal plants in real operating conditions.

At least 3% of wind production downtime due to breakdowns and maintenance problems that can reach up to 40%. This leads to production losses of over €2.9 billion worldwide annually. Our current SmartCast remotely connects SCADA and sensor data with a virtual database to monitor wind turbines. It involves algorithms based AI, cloud computing and data mining. The SmartGear product is a low cost Condition Monitoring System based on IoT technology which acquires raw data and connects with SmartCast Platform for further processing. The overall objective of the future Phase II Cloud Diagnosis project is to scale-up our SmartGear technology by introducing communication protocols that allow us to extract data from multiple devices allocated in the wind turbines and additional transducers. Additionally, SmartCast cloud diagnosis algorithms need to be improved. Our innovative solution will allow faster detection of wind turbine system failures through complex algorithms implementing intelligent sensor fusion, therefore, optimizing the performance of wind turbines. It does not require onsite visits but provides information online. In this way, our technology will be able to: Reduce wind turbine maintenance cost by 20%: €44 million annually in the Spanish market, €190 million per year in Europe and €440 million annually in the world market. Reduce wind turbine operation cost and component replacement of cost by 20%: A standard park of 50 MW (16 turbines) installation power working 2,100 hours per year faces production losses of at least €378,000 annually. Our system enables 20% savings of €75,600 (€4,725 per turbine). Currently, our SmartCast platform processes real-time data from SCADA and sensors by means of SVM (support vector machine) in 300 turbines. Our SmartGear Solution is present in two wind farms and is being rolled out in five more.

Our proposed technology uses bamboo for manufacturing a unique new bio-material which has the potential to replace most commonly used structural materials such as concrete, steel and timber. This novel process will not only ensure the sustainable supply of raw materials via environment friendly new solution in construction industry, but will also provide participating SME with the opportunity to derive an ongoing income. BAMBENG proposal outlines the opportunity to develop an innovative technological process which will produce a new constructional product, chemical free and environmental friendly (avoiding the use of toxic and polluting glues) with supreme technological, economic and environmental footprint performances. That would make BAMBENG advantageous competitor and feasible alternative as BAMBENG structural material, represents the best performing material for supporting structure for seismic building. BAMBENG is obtained by a simple chafing and pressure welding process, producing a semi-finished completely biological new component. The process in chemical free, energy saving and with a very low footprint, Compared with the most direct and similar competitive materials (wood, glulam and glubam) BAMBENG offers better technical performances and up to 45% of cost savings (based on Cost Structure Analysis). BAMBENG is worth to invest in because it is a combination of proven technology and novel application of demonstrable technology and methods which have both economic & environmental benefits: - Development of bigger structural components for buildings sector for easy substitution of current material like steel, aluminium, concrete, and even timber, - Development of building design to exceed seismic and hurricane requirements, - Transfer to other sectors such as interior and exterior architectural, packaging and design artefacts, - Improvement of local bamboo crops at EC level, and - Potential to license the technology to SMEs throughout the EU.

URBAN LEARNING gathers capitals and other large cities across Europe facing the common challenge of considerable population growth while being committed to significantly reduce fossil energy consumption and CO2 emissions. E.g. Stockholm grew by more than 12.000 people / a (1.5%); in the next 10 years Vienna has to build for 200.000 new people. Efficient and effective planning processes will be crucial for climbing this mountain. Vienna, Berlin, Paris, Stockholm, Amsterdam/Zaanstad, Warsaw and Zagreb aim to enhance the capacity of their local authorities on integrative urban energy planning, as response to new challenges from EU EPBD and RES directives as well as to changes of technologies and market conditions and the pressure to provide sufficient, affordable homes. The focus is put on the governance processes related to the (re-)development of concrete sites. While some cities already started ambitious urban development projects, the institutionalisation of these experiences is missing - despite awareness and willingness, due to lack of knowledge, lack of time and the need for collaboration across departments, which is not a common practice in many administrations in Europe. External stimulus is needed to overcome these barriers, and to address these issues collectively with external key stakeholders, such as DNOs and energy suppliers, and across cities. Focus will be on multi-disciplinary learning – concentrating on innovative technological solutions, instruments and tools as well as on innovative governance elements - and to capitalise this learning to institutionalise integrative urban energy planning. Improving the governance processes is expected to have significant energy impacts on homes and workplaces to be built and refurbished for over 3 million more people in the participating cities in the next 20 years: more than 1.700 GWh/a of energy savings and over 2.000 GWh/a renewable energy produced. Special emphasis is put on knowledge transfer to 150 more cities.

Wind power plays a crucial role in Europe’s strategy towards a zero-carbon, clean energy-powered economy. While efforts have primarily focused on the development of wind turbine technology, it starts to become evident that the planning associated with the end-of-service life of these equipment has been vastly neglected. Rotor blades are a particularly challenging component, as there is uncertainty about how to get rid of them properly and safely. Furthermore, their sheer huge size imposes important constraints on the trucking requirements for their transportation, which translates in significant costs for decommissioning and disposal. EcoBlade presents a disruptive concept which tackles the cumbersome transportation of decommissioned large size rotor blades. Our mobile separation platform relies on a modular system optimized for blade shredding and material separation. It also opens the path towards profitable and economically sustainable value chains aiming at the revalorization of the disposed blade material. Since existing experience on blades’ decommissioning is still limited, disposal best practices are still to be defined. Therefore, the development of our scalable platform currently holds important economic risks, given the uncertainty on market acceptance. For this reason, Frandsen Industri firmly believes that a two-phase approach under EU-funding is the ideal scenario, in order to initially assess the market for concept feasibility before initiating the innovation project. Ecoblade will serve as a key enabler for future decommissioning of rotor blades, allowing to save more than 60 M€ in transportation costs for the disposed blades during the 2020-2030 period. Moreover, the successful implementation of EcoBlade will also significantly enhance the profitability of Frandsen Industri, as its successful implementation would return an expected turnover of nearly €5 million, 5 years post-project, corresponding to over €1.6 million profit to our company.

INGECID is a renowned engineering company focused on developing innovative constructive processes applied to wind energy, where the cost of installations is dominated by the CAPEX of wind turbines (ca. 84%). While the need of minimizing the costs per installed MW has not been yet successfully addressed, the cost-effective redesign of taller wind turbine towers is now indispensable due to: a) the limited height (ca. 85m) and the fatigue vulnerability of actual towers, which hamper wind turbines harnessing higher wind velocities, at greater altitudes and for longer times (thus from delivering more electric power: P≈v3); b) the load needs for bearing heavier turbines (150 tons), and c) the costs of actual alternatives (hybrid steel/concrete and precast concrete towers) that have avoidable expenses of lifting, maintenance and transport. In this context, INGECID will become a reference within the tower manufacturing business (predicted global market investment of 17.11 bn€ by 2020, at a CAGR of 6.9%) by offering a 140m cost-competitive in-situ monolithic concrete tower solution for 3 MW wind turbines: LiraTower. This novel tower design, patent requested, surpasses actual solutions due to: a) its height (above hitherto reports of 120-137m); b) its unique design of internal and external tendons, which allow for excellent compressive strength (slender diameter of 4m), fatigue resistance and stiffness; and c) the cost reduction (ca. 30-40%) that in-situ technology offers over available solutions in market. With the proposed construction process and tower design, wind velocity increments of up to 8% and 26% higher output powers in comparison to 80m are now feasible at a competitive cost. Additionally, the drawbacks and transport costs of large tower sections, nearby prefabrication plants and on-site mechanizing are totally eliminated. Once in market, LiraTower would have a return on investment of 3.8 years, generating cumulative revenues of 9.53 M€ and 55 new direct jobs.

In recent years, research has shown that energy savings resulting from energy efficiency improvements have wider benefits for the economy and society such as increases in employment, GDP, energy security, positive impacts on health, ecosystems and crops or resource consumption. In order to develop more cost-effective energy efficiency policies and optimised long-term strategies in the EU, these multiple benefits have to be accounted for more comprehensively in the future. Although this field of research is growing, the findings are disperse and mostly have important gaps regarding geographic, sectorial or technical measure coverage and findings vary largely. This makes a consideration of multiple benefits in policy making and policy evaluation difficult today. The proposed project addresses these issues and aims at closing the identified gaps by five central research innovations: 1) data gathering on energy savings and technology costs per EU country for the most relevant 20 to 30 energy efficiency measures in the residential, commercial, industrial and transport sectors, 2) developing adequate methodologies for benefit quantification, monetisation and aggregation, 3) quantifying the most important multiple benefits and where adequate, monetising, 4) developing an openly available calculation tool that greatly simplifies the evaluation of co-impacts for specific energy efficiency measures to enable decision-making and 5) developing a simple online visualisation tool for customisable graphical analysis and assessment of multiple benefits and data exportation. Project outcomes can thus directly be used by stakeholders and will help to define cost-effective policies and support policy-makers and evaluators in the development and monitoring of energy efficiency strategies and policies in the future.
